llvm dev - Aug 2012 - [LLVMdev] Custom backend

Hello,

Currently I am developing a custom LLVM backend for HLS synthesis and 
design space exploration. The backend is supposed to change dynamically 
depending on the designer input, and re-linking llc every time there is 
a design change will drastically affect DSE time.

I have been stuck for some days while trying to load the generated 
shared library into llc without having to add the custom target into 
LLVM configure files. I know this was possible in previous releases, and 
was wondering if it is still possible in release 3.1 and I am doing 
something wrong.

Best Regards,

This is not possible for many releases already. In order to use custom backend
you have to register it at configure time. Maybe you should somehow
try to tune your workflow? E.g. use gold on Linux as linker?
